He indirectly indicated a shift in the key interest rate that has been kept at a record low of 1.25 percent since June last year by citing U.S. Federal Reserve Chair Janet Yellen’s recent comments.

“Yellen said it would be imprudent to keep monetary policy on hold until inflation is back to 2 percent as it could stoke bigger inflation problem later on and undermine financial stability in the long term, and I agree with this judgment,” he told reporters in a workshop on Friday when asked if the BOK could move to raise interest rates while demand-spurred inflation remained low.

The BOK will release revised outlook for this year’s economy and the next on Oct. 19 when it decides on monetary policy for October.
